OHLC in Streaming APIs

Please check the following query, which provides real-time OHLC data in streaming APIs.

  EVM(dataset: realtime) {
      orderBy: {ascendingByField: "Block_Time"}
      where: {Trade: {Side: {Currency: {SmartContract: {is: "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"}}, Type: {is: buy}}, Currency: {SmartContract: {is: "0xdac17f958d2ee523a2206206994597c13d831ec7"}}}}
    ) {
      Block {
        Time(interval: {in: minutes, count: 10})
      volume: sum(of: Trade_Amount)
      Trade {
        high: Price(maximum: Trade_Price)
        low: Price(minimum: Trade_Price)
        open: Price(minimum: Block_Number)
        close: Price(maximum: Block_Number)


What is the purpose of getting ’count’ in this example?

count in this case is the number of trades. It is an additional metric, you can remove it if you don’t need that information.
